RESUMO
The nucleotide recognition sequence for the restriction-modification enzyme of Escherichia coli A (EcoA) has been determined to be GAG-7N-GTCA. This sequence is fairly similar, but distinctly different from the two other type I restriction enzyme recognition sites known for E. coli B and E. coli K12, respectively. N6-adenosine methylation has been observed at nucleotide positions 2 and 12 within that sequence after modification by EcoA. As a reference point for mapping the single EcoA site in lambda, the position of lambda point mutation Oam29 has been determined also.
